Residues of eight perfluorinated compounds (PFCs) were investigated in 15 fish samples from the Danjiangkou reservoir and Hanjiang river (Xiangyang and Zhongxiang sections). The total concentrations of PFCs in fish muscles ranged from 2.01 to 43.8 ng g(-)(1) dry weight. The mean concentration of total PFCs from related muscles showed the following trend in various regions: Zhongxiang section < Xiangyang section < Danjiangkou reservoir. Perfluorooctane sulphonate (PFOS) was the dominant PFC in the fish liver samples from the Danjiangkou reservoir. The calculated hazard ratio (HR) of PFCs, for all fish muscle samples, was less than 1.0, and could be classified at safe levels for the general population. However, yellow croaker fish from the Danjiangkou reservoir and Hanjiang river-Xiangyang section had HRs of 0.2, indicating that frequent consumption of this contaminated fish may pose an unacceptable risk to human health.
对丹江口水库和汉江（襄阳和钟祥段）的 15 个鱼类样本中的 8 种全氟化合物（PFCs）残留进行了研究。鱼肌肉中 PFCs 的总浓度范围为 2.01 至 43.8ng/g 干重。各地区相关肌肉中总 PFC 浓度的平均浓度呈以下趋势：钟祥段<襄阳段<丹江口水库。全氟辛烷磺酸（PFOS）是丹江口水库鱼肝样品中主要的 PFC。所有鱼类肌肉样本中 PFC 的计算危害比（HR）均小于 1.0，可归类为普通人群的安全水平。然而，丹江口水库和汉江-襄阳段的黄鱼的 HR 为 0.2，这表明频繁食用这种受污染的鱼类可能对人类健康构成不可接受的风险。
